Aniline from aniline - water mixture

(i) ${\mathrm{CH}}_3-\mathrm{CH}={\mathrm{CH}}_2+\mathrm{HBr}$ $\stackrel{{\left({\mathrm{C}}_6{\mathrm{H}}_5\mathrm{O}\right)}_2{\mathrm{O}}_2}{\to }$ $\left(\mathrm{A}\right)$

(ii) ${\mathrm{CH}}_3-\mathrm{CH}={\mathrm{CH}}_2+\mathrm{HBr}$$\stackrel{}{\to }\left(\mathrm{B}\right)$

The type of isomeric relation between $\left(\mathrm{A}\right)$ and $\left(\mathrm{B}\right)$ is ?
